The face 26 is preferably in aplane subto fill the space outlined by the inner edge of the stantially perpendicular to the shoe bottom in the 55 to the shoe bottom.

position of the shoe in which it is presented to the machine.

After the shoe has been assembled and pulled over as described, cement such as pyroxylin cement is applied between the layers of the lasting allowance of the upper materials, for example between the upper 52 and a lining and if an insole is employed cement will be applied to the inner face of the lining 23 and to the margin the insole M. The side lasting operation is then performed by presenting the shoe to a machine of the kind described, the edge of the shoe being engaged by the edge gage i8 and the bottom of the shoe by the sole rest it at a distance from the edge gage 98 substantially equal to the width of the portion of upper to be overlasted. gripper 2?) acts to updraw and over-draw a portion of the upper materials and the wiper acts to wipe the tensioned upper over the shoe bottom and to press or squeeze the excess of lasting allowance against the face or abutment Winch is substantially perpendicular to the shoe bottom. Thus, the excess of lasting allowance is disposed in a position substantially perpendicular After the gripper reached the limit of its inward movement the shoe bottom, tack is i. -serted by the driver 2 1 through the upper materials i2 and E3 and into the wood of the last it and, course, through the insole if an insole is employed, the tack 39 being left upstanding to facilitate removal. The operations described formed progressively on successive portions of the upper materials until the sides of the and, if desired, the toe, are lasted as indicated in Fig 1, Where the overlasted portion of the upper is indicated by the numeral and the excess of lasting allowance by the numeral The heel-seat portion 35 of the upper may be lasted in the usual manner with tacks 3t com etely driven and clinched on the iron plate wi h which the heel end of the last is provided.

After the cement has set sufhciently to hold the upper in lasted position, the wthdrawn and the upper materials are trimmed away along the line formed by the angle between the lasting allowance 32 and the excess of lasting allowance 34, an overlasted portion of predetermined uniform width being thus produced.

Referring to Fig. 1, it will be seen that since the excess of lasting allowance between each pair of tacks is bent into a position substantially at right angles to the overlasted portion it resists bending in its own plane and forms a flange or truss between each pair of tacks which tends to hold the overlasted portion of the upper between those tacks from bending away from the shoe bottom and hence assists in holding the cemented sufaces tightly in contact. For this reason fewer tacks are necessary in lasting shoe by this method than by the usual method where the excess of lasting allowance laid flat against the shoe bottom. After trimming, the shoe -ay be finished by the attachment of an out-sole and heel in any usual or preferred manner.

Having thus described my invention. what I claim as new and desire to secure by Letters Patent of the United States is:

1. That improvement in methods of making shoes which comprises applying cement to the opposed surfaces of the lasting allowance of shoe upper assembled upon a last, progressively working successive portions of the shoe upper over the last bottom, turning each successive portion of the excess of lasting allowance into an upstanding position with respect to the last bottom by squeezing it into contact with a face perpendicular to the shoe bottom, said face being carried. by an abutment, utilizing the same face of the abutment repeatedly in lasting successive portions of the upper, and inserting a temporary fastening through the overlasted upper close to the abutment in each of its successive positions, whereby the excess of lasting allowance is presented in a position substantially perpendicular to the insole to facilitate its removal by a trimming operation.

2. In methods of cement-lasting shoes, that improvement which comprises providing a sole rest having a face perpendicular to the lasting sole disposed in the direction of the sole margin,

applying adhesive between the lasting sole and the marginal portions of the upper, progressively wiping the upper margin inwardly and squeezing the excess thereof against said. perpendicular face of the sole rest, and utilizing the same face of the sole rest repeatedly in lasting successive portions of th upper, whereby the excess of lasting allowance is presented in a position substantially perpendicular to the insole to facilitate its removal by a trimming operation.

3. In methods of cement-lasting shoes, that improvement which comprises providing a sole rest having a face perpendicular to the lasting sole disposed in the direction of the sole margin, applying adhesive between the lasting sole and the marginal portions of the upper, progressively wiping the upper margin inwardly and squeezing the excess thereof against said perpendicular face of thesole rest, utilizing the same face of the sole rest repeatedly in lasting successive portions of the upper, and inserting a temporary fastening through the overlasted upper close to said face in each of its successive positions whereby the excess of lasting allowance is formed to provide a truss-like flange between the fastenings.

method of cement-lasting shoes in which there is utilized a hand method lasting machine having instrumentalities for tensioning the upper and wiping a marginal portion thereof over an insole on a last including an abutment having a face perpendicular to the shoe bottom, which comprises the steps of applying adhesive between the insole and the marginal portions of the upper, presenting said upper and insole on a last for the action of said instrumentalities, and utilizing the wiping instrumentalities to squeeze the excess of lasting allowance against the perpendicular face of the abutment whereby the excess of lasting allowance is caused to remain in a position substantially perpendicular to the last bottom to facilitate trimming.

5. That improvement in methods of making shoes which comprises applying cement to the opposed surfaces of the lasting allowance of a shoe upper assembled upon a last, progressively working successive portions of the upper over a last bottom, squeezing each successive portion of the excess of lasting allowance into contact with face perpendicular to the shoe bottom, said face being carried by an abutment, and utilizing the same abutment repeatedly in lasting successive portions of the upper whereby after the cement has set the excess of lasting allowance is presented in a position substantially perpendicular to the insole to facilitate its removal by a trimming operation.
